IMPRCVEMENT IN DIES FOR FORGING CARRlAGE-STEP PADS.

Specification forming part of Letters Patent No. 148,589, dated March17, 1 874; application filed lluly 31, 1873.

To all whom fit may concern:

Beit known that I, HENRY M. BEECHER, of Vest Meriden, in the county ofNew Haz ven and State of Connecticut, have invented certain new anduseful Improvements in Dies for Forging Carriage-Step Pads, of which thefollowing is a specification:

In my improved dies the faces of both the upper and lower die-blocks arecorrugated in such a manner that the depressions in one block aredirectly opposite the elevations in the other, and in the lowerdie-block is a larger tapering recess or depression, in which thejunction of the step-pad and its shank is formed.

In the accompanying drawing, Figure l isa front elevation of dies forforging step-pads which embody my invention, and Fig. 2 is a plan orface view of said dies.

A designates the upper, and B the lower die. The faces of both of saiddies are corrugated-that is, covered with alternate elevations anddepressions so arranged that when the faces ofthe dies meet thecorrugations match into each other, as shown in Fig. l. C designates atapering recess extending from near the center of the lower die-block Bto one edge. This recess is designed to form an enlargement upon theunder side of the step-pad to strengthen it at the point of junctionwith its shank. The step-pad blank, after being formed in any ordinarymanner, is brought .to a proper heat, and subjected to pressure betweenthe dies A B, when the thin portion thereof will be corrugated tocorrespond with the face of the dies. The edges of the step-pad sostruck up may then be trimmed, when it is ready for the carriage-maker.

The direction of the corrugations may be varied, in order to produceycorrugated steppads of various designs. A step-pad of any contour, andof any size not exceeding that of the face of the dies, may be strucktherein.

I have designated the die which forges the upper side of the step-pad asthe upper die, Ste., but it is evident that either die may be placeduppermost in the drop or other forging machine, as may be desired. l,

Iclaim as my invention- The dies A B, corrugated upon their faces, andprovided with the tapering recess C, substantially as described, and forthe purpose set forth.
